Frequently Asked Questions
-
What is pound-force inch sq. second used for?
-
It is used to state rotor or flywheel inertia values in inch-pound engineering for small electric motors and servomotors.
-
Why convert to ounce-force inch sq. second?
-
Because it offers finer granularity for representing very small rotational inertias in applications like precision instruments.
-
Are these units applicable in SI system measurements?
-
These are English engineering units, but ounce-force inch sq. second can be approximately converted to SI units for comparison.
Key Terminology
-
Pound-force inch sq. second
-
A unit of rotational moment of inertia equal to pound-force multiplied by inch and by second squared used in English engineering.
-
Ounce-force inch sq. second
-
A smaller unit of moment of inertia using ounce-force multiplied by inch and by second squared, suitable for very small rotational inertias.
-
Moment of inertia
-
A measure of an object's resistance to angular acceleration, calculated as mass times length squared.
